python3容器化部署方案
Kubernetes (k8s) 部署 Nginx 网关通常涉及以下几个步骤:
1. 创建Nginx服务部署(Deployment):首先,你需要创建一个YAML文件(如`nginx-deployment.yaml`),描述Nginx镜像、副本数和配置。例如:
```yaml
apiVersion: apps/v1
kind: Deployment
metadata:
name: nginx-deployment
spec:
replicas: 2 # 指定复制的实例数
selector:
matchLabels:
app: nginx
template:
metadata:
labels:
app: nginx
spec:
containers:
- name: nginx-container
image: nginx:latest
ports:
- containerPort: 80
```
2. 应用部署:使用kubectl命令行工具将YAML文件应用到集群中:
```
kubectl apply -f nginx-deployment.yaml
```
3. 创建Service(服务):为了让其他服务能够访问Nginx网关,还需要创建一个Service来暴露端口,并定义其外部IP和端口号。例如:
```yaml
apiVersion: v1
kind: Service
metadata:
name: nginx-service
spec:
type: LoadBalancer
selector:
app: nginx
ports:
- protocol: TCP
port: 80
targetPort: 80
```
然后应用这个Service:
```
kubectl apply -f nginx-service.yaml
```
